Subject: [PATCH] Add multiple checks to supportsSoftButtonImages() (#1801)

This commit adds null checks and a List.size() check to PresentAlertOperation.supportsSoftButtonImages()
These checks prevent crashes and returns true when soft button capabilities are unavailable
This new behavior improves alignment with the other SDL libraries
